Figure 13. Lymphocele in a 72-year-old woman who presented with transplant dysfunction. The patient had undergone renal transplantation 11 years earlier. Axial T2-weighted MR image demonstrates a peritransplant fluid collection with homogeneous hyperintensity (arrow). These findings are consistent with an incidental lymphocele that did not result in significant parenchymal, vascular, or ureteral compression.
